​
Run SQL script and create schema for Datafold

To connect to MySQL, create a user with read-only access to all tables you wish to diff. Include read and write access to a Datafold-specific dataset:

-- Create a temporary dataset for Datafold to utilize
CREATE DATABASE IF NOT EXISTS datafold_tmp;

-- Create a Datafold user
CREATE USER 'datafold_user'@'%' IDENTIFIED BY 'SOMESECUREPASSWORD';

-- Grant read access to diff tables in YourSchema
GRANT SELECT ON `YourSchema`.* TO 'datafold_user'@'%';

-- Grant access to all tables in a datafold_tmp database
GRANT ALL ON `datafold_tmp`.* TO 'datafold_user'@'%';

-- Apply the changes
FLUSH PRIVILEGES;

Datafold utilizes a temporary dataset, named datafold_tmp in the above script, to materialize scratch work and keep data processing in the your warehouse.
